The bare bones of the argument are as follows.
"It\’s very important that the G8 get together and sort out the world\’s problems. Absolutely vital that governments act in this international manner.
Except, we don\’t want them to do any of the things that governments actually do, like impose biofuel targets or anything."
So they rather miss the obvious point that such international governmental action is always going to get co-opted by the special interests which will organise matters to their benefit, not the wider world\’s. In this case it\’s that unholy alliance of Greens, farmers and the politicians who are elected by their votes. On other matters the alliances will change, but it will always be x and y and the politicians elected by their votes. To the benefit of x and y and any connection with the wider world\’s interests will be entirely coincidental.
